If you want to generate some fake data, you can use Faker even outside factories or seeds, in any class.
Keep in mind: to use it in production, you need to move faker from "require-dev"
to "require"
in composer.json
1use Faker; 2 3class WhateverController extends Controller 4{ 5 public function whatever_method() 6 { 7 $faker = Faker\Factory::create(); 8 $address = $faker->streetAddress; 9 }10}
